View clinical trials related to Obstructive Sleep Apnea.
Filter by:Obstructive sleep apnea (OSA) is recurrent episodes of partial or complete obstruction of the upper airway during sleep that causes intermittent hypoxia and sleep fragmentation and leads to cardiometabolic and neurocognitive sequelae. Chronic intermittent hypoxia, sleep fragmentation of OSA, and insufficient sleep have been significantly associated with higher risks of neurocognitive impairment, including mild cognitive impairment (MCI) and Alzheimer's disease. Thus, sleep and circadian function might be modifiable neurocognitive impairment factors. The significance of the study is to understand the relationships of MCI with sleep apnea and sleep-related symptoms, which helps pave the groundwork for further research.
The goal of this clinical trial is to evaluate the feasibility and effectiveness of a ring-type blood pressure measurement device compared to a 24-hour ambulatory blood pressure monitoring device in patients with hypertension or suspected hypertension. The main question it aims to answer is whether the 24-hour blood pressure measurement accuracy of the ring-type blood pressure monitor is similar to that of the 24-hour ambulatory blood pressure monitor. To participate, subjects must wear a ring blood pressure monitor and an ambulatory blood pressure monitor simultaneously for 24 hours.
People with type 2 diabetes are at risk of complications linked with high blood sugars and these are monitored for in healthcare appointments. However, people with type 2 diabetes commonly suffer with additional health conditions that can affect the liver, heart and their breathing while sleeping. These conditions are thought to be caused by a similar underlying process that causes type 2 diabetes, as a result they are very common in people type 2 diabetes. Despite this they are not part of the routine health check for these people. Worryingly, current research suggests that the risk for developing these health problems, and direct complications of type 2 diabetes, can start at blood sugar levels below the threshold of type 2 diabetes. In a group of people said to have prediabetes. These people do not currently undergo annual healthcare appointments to monitor for these health complications or other linked health conditions. This study aims to pilot a new style of clinic to address these issues. The investigators will perform a multi-morbidity assessment, where they will look for several different health problems at the same time. The investigators will be looking at health problems linked with high blood sugars, this will include problems with the liver, heart, nerves, eyes, and participants breathing overnight. They have developed a clinic visit which uses questionnaires, simple examination techniques and modern devices to try and identify these health problems. An important part of healthcare is the burden it places on people with health problems, with this in mind the investigators will be giving the people involved in their study a voice to try and direct future research and healthcare, the investigators will ask them to provide feedback on their experience in taking part in the study and what their thoughts are in undergoing a longer but more comprehensive health appointment.
Obstructive sleep apnea (OSA) is a highly prevalent disorder that is associated with both cardiovascular and metabolic dysfunction, such as hypertension, increased blood glucose levels and diabetes, obesity, and nonalcoholic fatty liver. While continuous positive airway pressure (CPAP), the best available OSA treatment, has been shown to improve blood pressure in OSA, it does not appear to improve metabolic consequences of OSA, and other therapies for OSA-induced dysmetabolism are needed. Animal models of time restricted eating (TRE) demonstrate an improvement in glucose and lipid metabolism, even in the absence of a reduction of caloric intake. Some human studies have shown an improvement in metabolic dysfunction with TRE, though further well-designed studies are needed. The effects of TRE on metabolic dysfunction in patients with OSA, a population with a high predisposition to metabolic disorder, has never been examined. In this study, we will conduct a randomized clinical trial to assess the feasibility and efficacy of 12 weeks of TRE, versus standard eating (SE), to improve glucose regulation and cardiovascular health of participants with OSA.
The purpose of this research is to compare the impact of motivational enhancement therapy (MET), delivered by culturally congruent community health care workers (CHWs) versus usual care patients with previously untreated moderate-to-severe obstructive sleep apnea (OSA) on adherence to positive airway pressure (PAP) therapy.
Patients with chronic pain who use opioids appear to be at increased risk for breathing issues during sleep, termed sleep disordered breathing (SDB). Treatment of SDB often consists of use of a device during sleep that provides continuous positive airway pressure (CPAP) via a mask interface. However, this device is not effective or tolerated in all individuals. The goal of this study is to examine whether a medication called acetazolamide can improve SDB, as an alternative to CPAP treatment. The investigators will measure the improvement in SDB, as well as any change in symptoms, during a 1 week treatment with acetazolamide compared with 1 week of placebo (sugar pill). This study will help to provide data for longer term studies of treatment for SDB in patients who use opioids.
The purpose of this study is to assess whether oxygen supplementation during sleep improves working memory and other clinical and patient-reported outcomes among children who have Down Syndrome (DS) with moderate to severe Obstructive Sleep Apnea (OSA).
The goal of this clinical trial in adults with obstructive sleep apnea prescribed positive airway pressure therapy is to test the effects of a new patient-facing consumer wearable-based program (that involves provision of a consumer wearable that measures oxygen levels during sleep plus customized weekly reports to participants). The main question is to learn whether participants' use of positive airway pressure therapy will differ between the participants who receive the new program immediately versus delayed. Participants assigned to the delayed program will receive usual care while waiting for the program to begin.
The goal of this observational study is to learn about the use of non-invasive ventilation for treatment of obstructive sleep apnoea syndrome in children with Down Syndrome. The main questions it aims to answer are: - What is the impact of non-invasive ventilation on sleep behaviours and quality of life? - What barriers are faced by children and their families in establishing tolerance to non-invasive ventilation? Participants will be asked to complete questionnaires before and after starting treatment. Researchers will compare this data with the results of sleep studies and non-invasive ventilator downloads recorded as part of standard medical care. A sub-group of up to 20 participants will be invited to take part in 45-60 minute interviews exploring expectations, experiences and barriers encountered during non-invasive ventilation therapy.
A problem with breathing during sleep, called obstructive sleep apnea (OSA), likely increases the risk of stroke and is common in people who have had a stroke, present in about 2/3 of stroke survivors. There is also evidence that OSA predicts worse outcome after stroke. The question being addressed in the Stroke and CPAP Outcome Study 3 (SCOUTS3) is how to improve use of continuous positive airway pressure (CPAP) therapy to treat OSA when started during intensive stroke rehabilitation.
